Hi:

I would like to know your opinion about this images taken by the Cassini space probe in which there is an point that appears to be moving itself outwards the rings of the planet. Is a moon or could be a background star?

I suspect that Pat is probably in a pretty good position to know, he also identified a very tiny pixel as Telesto over on the Rev 016 Cassini thread. Nice one.

Not crap, a star. Crap needs the presence of evolved living beings to form.

That's gotta be a Cassini NAC frame, just look at the resolution!

I'm curious, though, is that a true color or false color composite?
